If your only talking about a select list with a few options then yes. But if your preloading js arrays with hundreds of options this will result in quite a hefty page. Try it, and then check the size of the resulting HTML page. Also using ajax it is very easy to expand to ANY number of related select lists. Doing this by pre-generating and populating js arrays will get more and more complicated and make the page bigger and bigger and slower to render.

Ehhhh... I don't think I'd totally agree with that. One load versus a load every time you make a selection. If it's all client side and in js arrays already, the changes would be much faster than an asynchronous call to another process to get the info. This all, of course, depends on how MUCH data we are talking about though. You don't want to overload a JS array on a windows 95 machine running IE 4.5 and 64 megs of ram ;-) As for the question. You can roll your own selects related or you could modify the onchange event of the twoselectsrelated's generated select with something like... document.forms['myformname'].myselctname.setAttribute('oncchange', 'callAFunciton()'); I'm sure I typoed something, just look up the setAttribute() method. You would want to call the above code AFTER the two selects have been rendered to the page. setAttributes DOES work in IE as well as FF regardless of what you read. There are just some attributes that it doesn't work very well with. I haven't found a definitive list of them anywhere, you'll just have to try it and see. Personally, id write my own from scratch. You should be able to find enough code on Google to piece something together. ...:.:.:.:.:.:.:.:.:.:.:.

These days your better off using AJAX to achieve the result of multiple related select lists. Its going to be a lot faster if your dealing with large amounts of data not to mention reducing loading time.

Maybe...and I cannot remember everything about it. In your twoSelects custom tag you should have the select that you want to get the information from. In that select try.. <select language="javascript" name="select1" onChange="text.value = select1.value"> <option value="test1">Test1</option> <option value="test2">Test2</option> <option value="test3">Test3</option> <option value="test4">Test4</option> </select> <input type="text" name="text"> ----- Original Message ----- From: "Che Vilnonis" <[EMAIL PROTECTED]> To: "CF-Talk" <cf-talk@houseoffusion.com> Sent: Thursday, December 07, 2006 10:30 AM Subject: Anyone familiar witht the CF_TwoSelectsRelated custom tag? > I ask because I would like to populate a text box named "Genus" with > the value that is selected from the custom tag value named "SelectedCatLevel2". > Does anyone know how I might do this?
